EROSION AND SEDIMENT CONTROL REPORT S.R. 0462 over Tributary to Strickler Run West Hempfield Township, Lancaster County 1.0 PROJECT OVERVIEW 1.1 Project Description The purpose of this study is to develop the Erosion & Sediment Control Plan needed for the replacement of the existing structure that carries S.R. 0462 (Columbia Avenue) over a tributary to Strickler Run in West Hempfield Township, Lancaster County. S.R. 0462 is classified as a rural minor arterial roadway. The project will extend from Station 12+50.00 to Station 15+50.00, a length of 300 feet. The project area is 1.13 acres with a total disturbed area of 0.66 acres. The existing bridge is a single-span reinforced concrete slab bridge, which carries two lanes and one auxiliary lane of S.R. 0462. The bridge has a clear span of 9-5 and a clear roadway width of 42-11¾. The bridge has a 6.8-foot underclearance and is skewed at 90 degrees to the centerline of roadway. The bridge shows signs of extensive deterioration. It is proposed to replace the existing structure with a 22-0 wide by 7-6 high precast concrete box culvert. The existing horizontal alignment will be maintained. The proposed roadway cross section will consist of two 11-foot lanes, one 10-foot auxiliary lane, and two 8-foot shoulders. The project area is located in a rural/agricultural region of Lancaster County. The project is located within the USGS Columbia East Quadrangle at N40 o 02' 30 latitude and W76 o 28' 00" longitude. The stream is perennial and the basin of Strickler Run is classified as a Warm Water Fishery (WWF) under Title 25, Environmental Protection, Chapter 93, Water Quality Standards. The bottom of the proposed replacement structure will be depressed a minimum of one (1) foot below the stream invert to establish the natural passage of the fish. 1.2 Project Duration The project has a proposed let date of September 2006. It is expected construction will be underway in the Spring of 2007 and the project will be completed by the Fall of 2007. 1.3 Plan Preparation Whitney, Bailey, Cox & Magnani, LLC has prepared erosion and sedimentation control plans for numerous projects from major highway projects to bridge replacement projects and site development plans. Erosion and sedimentation control submissions have been prepared for the following recent projects: S.R. 3025-A01 Bridge Replacement, Juniata County S.R. 0116-012 Bridge Replacement, Adams County WHITNEY, BAILEY, COX & MAGNANI, LLC Consulting Engineers, Architects, Planners, & Surveyors Page 1

O Neil, PE. Mr. O Neil was involved with the preparation of the erosion and sedimentation control plan for seven of the above referenced projects. His formal education consists of a Bachelors Degree in Civil Engineering from George Washington University and a Masters Degree from the University of Maryland. 2.0 SOIL INFORMATION Soils present in the project area include Ln Lindside silt loam and LdB Letort silt loam. The Lindside silt loam has inclusions that are hydric components. The Letort silt loam has 3-8 percent slopes. The Lindside silt loam and the Letort silt loam are classified as Prime Farmland. The existing land use of this soil within the project area is pasture, farms and single-family homes. Soils information for the project area is located in Appendix C. This information was obtained from the USDA-SCS Soil Survey of Lancaster County, Pennsylvania. The type of soil present within the project area is indicated on the soils map included in Appendix C. The soil is delineated on the Erosion and Sediment Control Plan. Based on the scope of the project, there are no limitations associated with the existing soil type. 3.0 DRAINAGE FACILITIES The proposed roadway is in a fill condition at all four corners of the bridge. The proposed roadway section is an open section with runoff dissipating down the fill slopes. Drainage improvements will be limited to replacing a section of existing 24 RCP storm drain pipe from Sta. 12+79 RT to Sta. 13+39 RT. The pipe will be redirected to discharge through the box culvert. A standard PENNDOT manhole will be installed at Sta. 12+79 RT to redirect pipe flow. No additional drainage will be discharged to the pipe due to proposed conditions. 4.0 TEMPORARY AND PERMANENT CONTROL MEASURES Several temporary control measures will be used for this project, which include silt barrier fence (18 high), sediment filter bags, erosion control mulch blanket, rock filter and WHITNEY, BAILEY, COX & MAGNANI, LLC Consulting Engineers, Architects, Planners, & Surveyors Page 2
